Question

A mechanical pencil has a mass of 47.4 grams. The volume of the pencil is 15.8 cubic centimeters. What is the density of the pencil?

Answer 1

3 g/cm^3

Step-by-step explanation:

Density can be determined by mass divided by volume, or P=m/V.

This would be 47.4 grams (mass) / 15.8 cubic centimeters (volume). The units are grams per cubic centimeter, noted as g/cm^3.

Answer 2

density = mass over volume
so
47.4g/15.8cm^3
=3g/cm^3
